This warranty applies only to the original end user of the clamp and is valid for 10 years from the date of purchase. GENERAL INFORMATION 1. The Model HBC is designed as a multipurpose clamp for lifting, positioning, and erecting structural beams and prefabricated sections. The split lower jaw also allows the operator to load the clamp on the ends of I Beams. 2. The HBC model has an over-center lifting shackle for stability when lifting structural beams from the fl ange and helps hold the beam in place. 3. Always choose the proper clamp and rated capacity for the material to be lifted. 4. The Model HBC maintains a 100% rated lift capacity with a forward sling angle up to 90 and a back sling angle up to 45 (Fig. 1). 5. The Model HBC has a locking handle that locks the clamp open to facilitate loading and unloading, and locks the clamp closed onto the material to be lifted for a more secure lift. Always store the clamp in the locked open position. 6. The locking handle also has a remote release design so, when needed, the operator can attach a tag line and safely lock the clamp open from a distance once the load has been securely positioned and the weight of the load is removed from the clamp. 7. The Model HBC is rated to lift material with a hardness up to 450 Brinell (48 Rockwell C) and is also available with stainless serrated grippers. For material harder than 450 Brinell, or for polished metals, use the Model HBC with smooth steel or smooth stainless non marring grippers. 8. The operator must read and understand the Operator s Manual before using a Safety Clamp. Conditions This warranty only covers defects in materials and workmanship and only if the clamp has been inspected, maintained, and operated within the guidelines of the clamp s Operation, Maintenance, and Repair Manual. The warranty does not cover wear to parts such as pins, grippers, lock springs, etc. If a defect is found within the warranty period, the clamp will be repaired or replaced by determination of the manufacturer. No warranty is given due to: regular wear; incorrect use; overload; modifi cation of the clamp; improper maintenance and/or repair. Figure 1 1
OPERATING AIDS 1. The Model HBC should not be used to handle material with temperatures below 0 F or above 225 F. These temperature restrictions apply to both the ambient temperature and the temperature of the material to be lifted. 2. Do not use the Model HBC for vertical movement of material. 3. Do not use clamps with serrated grippers on materials with a hardness in excess of 450 Brinell (48 Rockwell C). For material harder than 450 Brinell, or for polished metals, use the Model HBC with smooth steel or smooth stainless non marring grippers. 4. Do not lift material with mill scale, grease, or any other coatings that may prevent gripping surface from making solid contact with material. 5. Never exceed fi fteen degrees (15 ) side load with a Model HBC clamp (Fig. 2). 6. Never exceed a 90 frontward sling angle (Fig. 1). 7. Never exceed a 45 backward sling angle (Fig. 1). 8. Make sure the load to be lifted is properly balanced. Multiple clamps may be needed to balance the load. 9. Never lift or transfer material over or near people. 10. Always lock the clamp closed before making a lift. Don t make a lift with the lock in the open or locked open position. 11. Do not lift clamp with an open-end hook. 12. Do not alter clamp. Do not weld, grind, or modify the clamp in any way. 13. If a clamp has been overloaded or damaged in any way, take the clamp out of service immediately. 14. Do not improvise and misuse the clamp. Always use correct clamp for the lift. OPERATION Inspection Before and After Each Use The Safety Clamps inspection procedures meet and/or exceed the requirements set forth in the ASME B30.20 Below-the-Hook Lifting Devices guideline. 1. Before using any Safety Clamp, the operator must read and understand the Operator s Manual in its entirety. 2. All Safety Clamps should be inspected before and after each use. Do not use if any components are bent, elongated, gouged, nicked excessively, worn, and/or damaged. Make sure that nuts, bolts, pins, and other mechanical fasteners are tightened and secured. 3. Be sure the clamp to be used is the proper clamp for the job. Check the rated capacity and jaw opening stenciled on the Identifi cation Tag. Both should equal or exceed the requirements for the load to be lifted. Warning: Never exceed the rated capacity or use on material that is not within jaw range of the clamp. 4. Do not use the clamp if the Identifi cation Tag or the Warning Tag is missing or illegible. 5. Inspect the gripping cam(s) (SC-50 or SC-42, Fig. 5) for wear and defects. Gripping surfaces must be sharp and free of foreign matter. 6. Inspect the condition of the body for wear, damage and distortion, particularly in the area of the jaw opening and holes for pins. 7. Inspect the lifting shackle (SC-10, Fig. 5) and all pins for wear and damage. 8. The lock spring (SC-61, Fig. 5) must have a defi nite amount of tension when the lock is moved to the Lock Closed position, with minimal material in the clamp. 9. Remove from service and tag any clamp in need of repair indicating the problem area and bring to supervisor s attention. A full periodic inspection is to be performed at this time by qualifi ed personnel (see periodic inspection, p. 9). The next periodic inspection will be timed from when the clamp is returned to service. 10. Make sure that all roll pins are securely in place. 11. Never use a clamp in need of repair. 2 3
OPERATION Loading the clamp 1. When placing the clamp onto the material, the clamp should be in the locked open position with the gripping cam(s) out of the jaw opening. This helps to prevent damage to the gripping teeth during loading. 2. Center the clamp so the load is balanced when lifted. When using more than one clamp, make sure the clamps are positioned to share equal loads. 3 Ensure the clamp is positioned so the direction of force applied by the crane is in line with the lifting shackle (Fig. 2). WARNING: Never exceed 15 side loading with a Model HBC clamp (Fig. 2). 4. Place the jaw of the clamp around the material to be lifted. Make sure the clamp is positioned so the edge of the material is 1/8 to 1/4 from the back of jaw opening and the gripping surfaces are in full contact with the material. 5. Secure the clamp in the lock closed position. Do this by seating the material in the clamp jaw opening with the lower jaw against the material and rotating the lock handle (A, Fig. 4) until the lock inside the body is positioned against the stop (B, Fig. 4). The gripping cam(s) (C, Fig. 4) will rotate into the jaw and engage the material at the point where they will bite into the material once the load is applied. 6. Once the clamp is properly locked closed onto the material, the clamp is now ready to make a lift. WARNING: The operator and all other personnel should be fully clear of the lifting area. OPERATION Lift and Transfer of Material 1. As the operator begins to make the lift, ensure the load is balanced. If the load is not balanced, lower the material and adjust the position of the clamp(s) accordingly and follow the guidelines under the Loading the clamp section. Never lift or transfer material when the load is not balanced. 2. During transfer of the material from one location to another, the operator should ensure the load is steady during transfer and not allow the load to bump or strike other objects. 3. Upon reaching the material s destination, lower the clamp and material to a secure position until the tension is relieved on the lifting shackle (D, Fig. 3). 4. Once the load is at rest and secured, rotate the lock handle (A, Fig. 3) to the locked open position. This will disengage the clamp from the material and lock the gripping cam(s) (C, Fig. 3) out of the jaw opening to protect the gripping teeth. If the clamp is in a hard to reach position, push in on the lifting shackle (D, Fig. 3) after the lock handle (A, Fig. 3) is released to help facilitate locking the clamp open. Note: Always store the clamp in the locked open position to protect the grippers and help ensure longer use. Warning Operator must follow all guidelines in each section before making a lift.
